Optical media types

There are a number of optical disk media types that can be used with the 3995 optical device. You can use the following media types in the optical environment:

5.25-inch, single-density, WORM optical disk media
5.25-inch, double-density, WORM optical disk media
5.25-inch, single-density, rewritable optical disk media
5.25-inch, double-density, rewritable optical disk media
5.25-inch, quad-density, WORM optical disk media
5.25-inch, quad-density, rewritable optical disk media
5.25-inch, 8x-density, rewritable optical disk media
5.25-inch, 8x-density, WORM optical disk media

Note: Unless otherwise stated, continuous composite WORM (CCW) media is included wherever the terminology double-, quad-, and 8x-density WORM media is used. For more information on these media types and the libraries and drives that use them, see Table 1.

When an object is stored using the OSREQ STORE macro, it is assigned to a specific Object storage group by the SMS storage group ACS routine. If the object is stored on an optical volume, OAM selects an optical volume residing in one of the optical libraries associated with the Object storage group to which the object has been assigned. See the description of the DEFAULT MEDIA TYPE parameter in Defining real 3995 libraries for more information concerning the DEFAULT MEDIA TYPE option.
